PENGEMBANGAN PROTOTIPE SISTEM MONITORING KELEMBABAN TANAH UNTUK PENGONTROLAN POMPA AIR OTOMATIS BERBASIS INTERNET OF THINGS

Abstract

Abstract - This research aims to determine: (1) the average output voltage (signal out) of the sensor used to control
the relay, (2) the average voltage when the system is operating normally. (3) The average current when the system is operating
normally.The methods used in this study is the Research and Development (R&D) method, which consists of several stages:
potential and problem identification, data collection, product design, design validation, design revision, product testing,
product revision, and field testing.The results indicate that: (1) the average output voltage used to control the relay is 1.28
volts, (3) the average system voltage during normal operation is 4.54 volts, (4) the average system current during normal
operation is 97.5 milliamperes
